When a particular food is added to the refrigerator, a corresponding icon for the food object may be selected and placed in the image of the refrigerator using the food management menu. The food management menu may be used to quickly track and view the contents of the refrigerator. Moreover, food icons may be sorted based on frequency or category in the food object selection area.

A frequency tab 810 and a category tab 820 may be displayed at the upper end of the food object selection area, as shown in FIG. 8A. If the frequency tab 810 is selected, icons of food objects are sorted in order of decreasing input frequency at in the food object selection area. That is, an icon corresponding to a food object which is frequently stored by a user may be displayed at the upper end. Here, a color of a selected food object icon 831 may be changed or otherwise highlighted when selected, e.g., touched. The list of stored item icons may be scrolled in the vertical direction using, for example, a flick or drag input. The frequency of use may be based on overall frequency of use, based on a particular user or on information received from a server. For example, the frequency of use may be tracked for a particular user or it may be based on frequency of use by a community of users.

If an item to be stored is chicken, for example, in order to input information that the item is stored in a specific compartment 841 of a storage chamber, the chicken icon 831 may be activated by maintaining a touched state of the chicken icon 831 in the food object selection area for a designated time, as illustrated in FIG. 8B, and thus a movable icon 833, separate from the chicken icon 831, may be displayed.

Thereafter, when the separated icon 833 is dragged from the position of the original icon 831 to a desired storage chamber, as shown in FIG. 8C, and then touch of the icon 833 is released, a detailed information popup window 850 may be displayed, as shown in FIG. 8D. In more detail, the icon 831′ corresponding to the food object, +/− buttons 851 to adjust the quantity of the food object, and a storage period change button 853 may be displayed on the popup window 850.

FIG. 9 is a view illustrating one example of setting of a storage period from among information on a food object through the display of the refrigerator in accordance with an embodiment of the present disclosure. The storage period for each food object may be stored. If the storage period change button 853 of FIG. 8 is selected, a period change popup window is displayed, as shown in FIG. 9.

An expiration date may also be set automatically using default values.

If change has been completed, a user may select a store button 930 to store the changed storage period, or select a cancel button 940 to cancel change of the storage period. Storage periods of food objects set in the above-described manner may be displayed on a storage period notification widget, which will be described later, in the order that the storage period expiration dates of the food objects are near.

FIGS. 10A and 10B are views illustrating one example of selecting various storage chambers of the refrigerator through the display in accordance with the embodiment of the present disclosure. It is assumed that FIGS. 10A and 10B illustrate a state after storage of the information on chicken has been completed through the process shown in FIGS. 8A to 8D and FIG. 9. Hence, in FIG. 10A a chicken icon 1020 is displayed in area 1010 of a storage chamber, indicating that chicken is stored at the corresponding position of the refrigerator 100.

Storage chamber 1030 may be a separate compartment of the refrigeration chamber which may be opened from the outside without opening the refrigerator door 8. The storage chamber 1030 may be closed to the main refrigeration chamber such that opening the storage chamber 1030 does not affect the cold air in the main refrigeration chamber. For example, frequently accessed items may be stored in the storage chamber 1030 to conserve energy. Storage chamber 1030 may be referred to as a “magic space” or “magic compartment” and may have a separate temperature control than the main refrigeration chamber or the freezing chamber.

If the storage chamber 1030 is selected from the image of the interior of the refrigerator, the displayed image may be changed to show the interior of the storage chamber 1030. Here, the image of the remaining portions of the refrigerator may be illustrated as being closed to highlight the storage chamber 1030 as well as to provide a physically accurate and aesthetically pleasing graphical user interface, as shown in FIG. 10B. A process of adding food objects and associated information into the magic space is the same as the previously described process for the main storage chambers within the refrigerator, and a detailed description thereof will thus be omitted. Further, a selection of the image of the refrigerator outside the magic space may revert the image to the interior image of the main storage chambers.

Next, selection of food objects according to category will be described with reference to FIGS. 11A and 11B. FIGS. 11A and 11B are views illustrating one example of inputting of information for stored food according to category through the display of the refrigerator in accordance with an embodiment of the present disclosure.

First, if a category tab 1120 provided at the upper end of the food object selection area is selected, icons corresponding to categories of food objects are displayed under the category tab 1120, as shown in FIG. 11A. Then, if a fruit icon 1121 is selected, icons 1130 corresponding respective fruits are displayed below the tab 1120, as shown in FIG. 11B. If a user desires to input storage information on a specific fruit, one of the fruit icons is activated and is then dragged and dropped to one area of the storage chamber. Detailed information associated with the specific fruit may be confirmed/amended through the detailed information popup window which will be displayed later, in the above-described manner with reference to FIGS. 8A to 8D.

FIGS. 12A and 12B are views illustrating one example viewing information for food stored in a storage chamber through the display of the refrigerator in accordance with an embodiment of the present disclosure. In this example, it is assumed that FIGS. 12A and 12B illustrate a state in which storage information on 4 kinds of food objects in one storage chamber have been previously input. Further, it is assumed that only icons corresponding to 2 kinds of food objects which were most recently stored in each storage chamber are displayed.

With reference to FIG. 12A, an indicator 1220 may be displayed together with the food icons to indicate the number of types of items stored in a specific storage chamber 1210. The indicator 1220 may be configured to be displayed only when the number of types of the food objects in the corresponding storage chamber exceeds a prescribed number (e.g., 2), or the indicator 1220 may be displayed at all times. Further, the numeral displayed on the indicator 1220 may indicate the number of different types of food objects, or the indicator 1220 may indicate the quantity of a particular food object. That is, when the same food object is input twice, if the numeral displayed on the indicator 1220 indicates the number of kinds of food objects, the indicator 1220 displays 1. Alternatively, if the numeral displayed on the indicator 1220 is configured to indicate the quantity, the indicator 1220 displays 2. In this case, each food icon may have a separate indicator 1220 positioned adjacent thereto.

Here, if a user selects the corresponding storage chamber, an area corresponding to the storage chamber may be activated and magnified at a designated rate, as shown in FIG. 12B. Simultaneously, under icons 1241 and 1243 of 2 kinds of food objects, the names of the food objects may be displayed. Scroll buttons 1231 and 1233 may be provided to view other food objects positioned to the left and right of the icons 1241 and 1243.

The case in which a bean curd icon 1243 is selected in FIG. 12B will be described with reference to FIGS. 13A and 13B. FIGS. 13A and 13B are views illustrating one example of viewing and editing detailed information for a food object in the storage chamber through the display of the refrigerator in accordance with an embodiment of the present disclosure.

When the bean curd icon 1243 is selected, as shown in FIG. 12B, a popup window to confirm/change detailed information on bean curd may be displayed, as shown in FIG. 13A. Here, the shape and configuration of the popup window may be similar to that of FIG. 8D. That is, an icon 1310 corresponding to the food object, +/− buttons 1320 to adjust the quantity of the food object, and a storage period change button 1330 may be displayed in the popup window 850.

Further, a recommended dish view icon 1340, an icon 1350 to add the corresponding food object to the shopping list, a wastebasket icon 1360 to delete storage information on the corresponding food object, and a confirmation icon 1360 and a cancellation icon 1370 may be displayed. However, the popup window of FIG. 13A differs from the popup window of FIG. 8D in that the popup window of FIG. 13A displays the detailed information for a food object which was previously added and FIG. 8D is provided to add a food object. Moreover, when the recommended dish view icon 1340 is selected, a popup window 1390 including recommended dishes using the corresponding food object as a material may be displayed, as shown in FIG. 13B.

FIGS. 14A to 14D are views illustrating one example of selection of a food object through a voice command in the refrigerator in accordance with the embodiment of the present disclosure. When a microphone icon 1410 at the lower end of the food object selection area is selected, as shown in FIG. 14A, the controller 280 activates the microphone 222, and when preparation to input a voice has been completed, a popup window 1420 to instruct a user to input a voice may be displayed, as shown in FIG. 14B. When the input voice is recognized, a popup window 1420 including an icon of a food object according to a result of recognition may be displayed, as shown in FIG. 14C.

If a food object desired by a user through a voice command is garlic, the user selects an icon 1431 corresponding to garlic, and thus, a window 1440 including an inner space graphic 1450 of the refrigerator may be displayed, as shown in FIG. 14D. When a storage chamber 1451 within the inner space graphic 1450 of the refrigerator is selected, detailed information for the food object may be entered. The subsequent process to enter the detailed information is the same as or similar to the process of the above-described detailed information popup window shown in FIGS. 8A to 8D, and a detailed description thereof will thus be omitted. If recognition of voice input is failed, information notifying recognition failure and requiring the user to re-input a voice may be additionally displayed.

FIGS. 15A and 15B are views illustrating one example of selection of a food object through a virtual keyboard in the refrigerator in accordance with the embodiment of the present disclosure. When a keyboard icon 1410 at the lower end of the food object selection area is selected, as shown in FIG. 15A, a virtual keyboard 1530 may be displayed, as shown in FIG. 15B. Text input through the virtual keyboard 1530 may be displayed in an upper area 1520, and when input of a desired search word has been completed, a user may select a search button 1540.

In one embodiment, the voice command and virtual keyboard functions may be used to find a specific food object which was previously added to the refrigerator. For example, if a large number of food objects have been entered using the food management menu, it may be difficult to locate a particular food object in the refrigerator. In this case, the voice command or virtual keyboard may be used to input the name of the desired food to search the refrigerator for that item.

Next, a process of storing a new food object which is not found in the food library will be described with reference to FIGS. 16A to 16D. FIGS. 16A to 16D are views illustrating one example of registration and storage of a new food object through the virtual keyboard in the refrigerator in accordance with the embodiment of the present disclosure. In FIGS. 16A to 16D, it is assumed that information regarding to an item “potato snack” is not stored in the memory 250 and an icon according to frequency and an icon according to category corresponding thereto are not present.

First, a user inputs a word “potato snack” through the virtual keyboard and executes search, as shown in FIG. 16A. However, since information regarding to the item “potato snack” is not stored in the memory 250, a menu 1610 to add a kind of food object called “potato snack” is displayed, as shown in FIG. 16B. When the food object kind addition menu 1610 is selected, a popup window 1620 to confirm whether or not the corresponding food object is added to a user database may be displayed, as shown in FIG. 16C. If “yes” to add the corresponding food object is selected within the popup window 1620, a window including the inner space graphic of the refrigerator may be displayed, as shown in FIG. 16D. A subsequent process including setting of detailed information after a storage position has been selected is the same as the above-described process.

Storage information on the above-described food object may be transmitted to an external device, or information stored in the external device may be called to the refrigerator. Here, the external device may be a mobile terminal, such as a smart phone, or a server. Connection with the external device may be executed through the wireless communication unit 210. For this purpose, a method of inputting a command will be described with reference to FIGS. 17A to 17D.

FIGS. 17A to 17D are views illustrating one example of execution of input of a command to communicate with an external device in the display of the refrigerator in accordance with the embodiment of the present disclosure. First, if storage information on a food object currently stored in the memory 250 is desired to be sent to an external server, a user may select a sending button 1710 at the lower end of the food management menu, as shown in FIG. 17A. Thereby, a popup window indicating a sending state may be displayed, as shown in FIG. 17B.

Thereby, a popup window indicating a retrieving state (calling state) may be displayed, as shown in FIG. 17D.

Further, an icon displayed on a storage chamber in the refrigerator inner space graphic may be added to the recipe or the shopping list. FIGS. 18A to 18D are views illustrating one example of addition of a food object displayed on the display to another menu in the refrigerator in accordance with an embodiment of the present disclosure.

First, a user may select a storage chamber 1810, in which a food object to be added to the recipe is stored, to activate the corresponding storage chamber 1810. Once the storage chamber 1810 has been selected, an icon 1820 of the food object to be added may be dragged to the recipe menu 1830 provided at the lower end of the food management menu, as illustrated in FIG. 18A. A popup window notifying a result of addition may be displayed, as shown in FIG. 18B.

Further, the user may select the storage chamber 1810, in which a food object to be added to the shopping list is stored, to activate the corresponding storage chamber 1810, and drag an icon 1820 of the food object to be added to a shopping list menu 1840 provided at the lower end of the menu, as illustrated in FIG. 18C. A popup window notifying a result of addition of the food object to the shopping list may be displayed, as shown in FIG. 18D.

An icon displayed on a storage chamber on the refrigerator inner space graphic may be deleted. FIGS. 19A to 19D are views illustrating one example of deletion of a food object displayed on the display of the refrigerator in accordance with the embodiment of the present disclosure.

First, a food object may be deleted by activating a storage chamber in which the food object is stored and then dragging an icon 1910 of the food object desired to be deleted to a wastebasket 1920, as illustrated in FIG. 19A. Here, deletion of the food object may not only delete the icon displayed on the storage chamber, but also delete storage information for the food object corresponding to the deleted icon (e.g., quantity and expiration date information). A popup window 1930 notifying that the corresponding food object has been placed in the wastebasket 1920 may be displayed, as shown in FIG. 19B.

Further, deletion of a designated range is possible. Specifically, when a menu button 1940 provided at the upper end is selected, as illustrated in FIG. 19C, a menu 1950 may be displayed at the lower region which allows a selection of deletion ranges, as shown in FIG. 19D. That is, deletion of a designated range, such as deletion of the entirety of the freezing chamber, deletion of the entirety of the refrigerating chamber, deletion of the entirety of the magic space or deletion of the entirety of the refrigerator may be specified. When the range is specified, information associated with food objects stored in the corresponding range may be deleted at the same time.

In one embodiment, when a food object is deleted from a storage chamber (or moved to a recipe), the food object may be automatically added to the shopping list. For example, when an item is dragged into the wastebasket icon 1920, this may indicate that the particular item has been consumed by the user. Hence, a popup window may be provided to inquire whether the consumed food object should be placed in the shopping list to replenish supply of the consumed food object. In one embodiment, deleted food objects may be placed in the shopping list based on its frequency of use. For example, the refrigerator may track the frequency of use of food objects, and food objects which are accessed frequently may be automatically placed in the shopping list while food objects which are not accessed regularly may not be automatically added to the shopping list. A list of food objects for automatic addition to the shopping list may be stored in the memory with user preference settings.

In one embodiment, the food management menu may be used in conjunction other types of systems for tracking contents of a refrigerator. For example, the food management menu may be used together with a RFID system to track and manage the contents in the refrigerator. For example, as food is placed in a particular region of the refrigerator, the RFID system may sense the type and quantity of the newly placed food. Then, a corresponding icon associated with the newly placed food may be displayed in the image 720 of the refrigerator. Additional information may be entered, such as expiration dates, using the display 200 as previously described. Alternatively, expiration date information may be set using default values based on the detected food identification. Moreover, RFID may be used to sense when food is removed from the refrigerator, and the display may be updated accordingly.

FIGS. 29A to 29D are views illustrating one example of a weather widget and a method of setting a region in the weather widget displayed on the display of the refrigerator in accordance with an embodiment of the present disclosure. First, when the weather widget is selected from the home screen through a touch, detailed weather information including current weather, temperature, a current region, a weekly weather forecast, etc. may be displayed, as shown in FIG. 29A. Here, when a region setting button 2910 arranged at the right of a map indicating which region the currently displayed weather corresponds to through different colors is selected, a popup window 2920 for region setting may be displayed, as shown in FIG. 29B. If a region list is not displayed at a time on the popup window 2920, the region list may be scrolled in the vertical direction through drag/flicking input.

If the Seoul/Kyungki region is selected from the region list, a popup window 2940 including a sub-region list is displayed, as shown in FIG. 29C. Here, if a designated region is specified, a popup window 2950 indicating receiving weather of the corresponding region from an external server may be displayed after setting of the region has been completed, as shown in FIG. 29D. Thereafter, the weather widget displays weather of the changed region.

FIG. 30 is a view illustrating one example of use of the storage period notification widget displayed on the display of the refrigerator in accordance with an embodiment of the present disclosure. When a user selects the storage period notification widget from the home screen through a touch, an icon 3010 of a food object, storage period expiration of which is near, is displayed, as shown in FIG. 30. The displayed icon 3010 may be dragged to a recipe menu 3020 provided at the lower end, thus being capable of being added to the material area of the recipe menu. Further, if the displayed icon 3010 is dragged to a shopping list menu 3030 provided at the lower end, the icon 3010 may be added to the shopping list menu.

Refrigerator Management

When a user touches the refrigerator management icon 645 (with reference to FIG. 6) from among the several menu icons provided at the lower end of the display 241, an menu 3101 for refrigerator management may be displayed, as shown in FIG. 31.

There may be 6 refrigerator management menu items. That is, the 6 refrigerator management menus items may include a freezing chamber temperature setting button 3111, a refrigerating chamber temperature setting button 3112, a special freezing setting button 3113 increasing the freezing rate of the freezing chamber, a special freezing chamber operation setting button 3114, a filter device setting button 3115 and a smart power saving operation button 3116.

Temperature Adjustment

Each of the freezing chamber and refrigerating chamber temperature setting buttons 3111 and 3112 includes a touch button to lower and raise temperature, and a window showing the current temperature of the freezing chamber or the refrigerating chamber. The temperature may be displayed in Celsius or Fahrenheit.

Each of the special freezing setting button 3113, the special freezing chamber operation setting button 3114 and the smart power saving operation button 3115 may include a touch button to select ‘operating’ and ‘off’, and the filter device setting button 3115 includes an ‘auto’ button for automatic operation, a ‘power’ button to improve sterilizing performance during operation, and a ‘off’ button.

A virtual refrigerator in which a refrigerating chamber and a freezing chamber are completely opened is displayed on the refrigerator management menu, and the positions of a special freezing chamber and a filter device provided in the freezing chamber and the refrigerating chamber are displayed on the virtual refrigerator.

Buttons regarding the above-described 6 menu items are arranged around the virtual refrigerator, and a user may touch these buttons to operate the refrigerator. Here, the respective buttons are touch buttons, and these touch buttons may be capacitive switches which are operated through reaction with a human body close to the buttons by a designated distance or an object having static electricity without mechanical operation.

As shown in FIG. 32, in order to adjust the temperature of the freezing chamber or the refrigerating chamber, the user operates the freezing chamber temperature setting button 3111 or the refrigerating chamber temperature setting button 3112. Here, the freezing chamber and the refrigerating chamber temperature setting buttons 3111 and 3112 include an up button and a down button so as to raise and lower the respective temperatures of the freezing chamber and the refrigerating chamber.

When these buttons are pressed to adjust temperature, numeral of a temperature and graduations of thermometers displayed on a freezing chamber temperature state window 3111 a or a refrigerating chamber temperature state window 3112 a may be changed, as illustrated in FIG. 32.

Temperature adjustment of the freezing chamber or the refrigerating chamber is executed according to opening and closing operation of a cold air damper, change of an operation factor of the compressor, on/off of the cold air fan, or change of a rotating velocity of the cold air fan.

Special Freezing Operation

As shown in FIG. 33, when the ‘operating’ button of the special freezing setting button 3113 in the refrigerator management menu is selected, the color of the entirety of the freezing chamber F of the virtual refrigerator may be activated (e.g., color changed or the chamber highlighted), and the controller causes freezing within the actual freezing chamber 5 (with reference to FIG. 5) to be more rapidly executed than in the general freezing operation mode. That is, the freezing chamber in the special freezing operation mode more rapidly reaches a target temperature than in the general freezing operation mode. The special freezing operation may be executed while increasing the rotating velocity of the cold air fan.

Further, when a designated time period has elapsed from the time the ‘operating’ button of the special freezing setting button 3113 is pressed, the window of the freezing chamber F of the virtual refrigerator may be deactivated and the special freezing operation automatically turned off. Moreover, when the ‘off’ button of the special freezing setting button 3113 is pressed before the designated time has not elapsed, the special freezing operation is finished and the refrigerator enters the general freezing operation mode.

Special Freezing Chamber Operation

As shown in FIG. 34, when the ‘operating’ button of the special freezing chamber setting button 3114 is selected, the color of the special freezing chamber SF of the virtual refrigerator may be activated. The special freezing chamber SF means a special freezing chamber which has a lower temperature than the freezing chamber and a relatively high freezing velocity (or rate) in order to store food, such as meat, in the optimal state.

Special freezing shown in FIG. 33 corresponds to rapid freezing of the entirety of the freezing chamber, and is used when a large amount of items are put into the freezing chamber. Therefore, if the special freezing operation is executed, the compressor and the cold air fan are operated for a longer time than in the general freezing operation.

On the other hand, the special freezing chamber shown in FIG. 34 corresponds to a storage space that is separately provided in the freezing chamber, and special freezing chamber operation refers to concentration of cold air into the separate storage space. If a relatively small amount of meat or fish, as compared to the state of FIG. 33, is required to be placed in the special freezing chamber so as to be rapidly frozen, the special freezing chamber operation is executed. For this purpose, a cold air fan and/or a cold air damper that concentrate cold air in the direction toward a duct connected to the special freezing chamber may be provided.

Filter Device Operation

FIGS. 35A to 35C are views illustrating display states regarding operation of the filter device 295 (with reference to FIG. 1). Although FIGS. 35A to 35C state the filter device 295 as a sterilization filter, the scope or function of the filter device 295 is not limited to the sterilization filter.

The filter device 295 in accordance with the present disclosure may execute a sterilization function of removing viruses or bacteria from the inside of the refrigerator and a deodorization function of removing odors from the inside of the refrigerator. As shown in FIGS. 35A and 35B, when the ‘auto’ button or the ‘power’ button of the filter device setting button 3115 are selected, the color of the refrigerating chamber R of the virtual refrigerator on the display 214 may be changed or highlighted. Simultaneously, the filter device 295 provided in the refrigerating chamber 6 (with reference to FIG. 1) of the main body of the refrigerator may be operated to filter air within the refrigerating chamber 6.

The lighting device 296 (with reference to FIG. 1) is provided around the filter device 295 of the refrigerating chamber 6. When the ‘auto’ button or the ‘power’ button is touched, the lighting device 296 is turned on while operating the filter device 295 to indicate the operational state of the filter device 295.

Here, operation of the filter device 295 when the ‘auto’ button is touched and operation of the filter device 295 when the ‘power’ button is touched are basically the same. However, operation of the filter device 295 when the ‘auto’ button is touched and operation of the filter device 295 when the ‘power’ button is touched are different in that the ‘power’ setting may require increased rotating velocity and an operating time of a fan unit 295 b (with reference to FIG. 1) of the filter device 295. Further, as shown in FIG. 35C, when the ‘off’ button is selected, operation of the filter device 295 (with reference to FIG. 1) is stopped, and the activated color of the refrigerating chamber R of the virtual refrigerator is no longer activated.

As shown in FIG. 36, if the life span of the filter unit 295 a (with reference to FIG. 1) of the filter device 195 (with reference to FIG. 1) is ended, and thus replacement of the filter unit 295 a is required, a replacement button 3601 in the refrigerating chamber R of the virtual refrigerator of the display 241 may be displayed, e.g., in a popup window. Therefore, a user or an AS mechanic may replace the filter unit 295 a with a new one upon seeing the popup state of the replacement button 3601. When the replacement button 3601 is pressed for a designated time (for example, 5 seconds), the life span timer may be reset and the replacement button 3601 may disappear.

Power Saving Command

FIGS. 37 to 40 are views illustrating a power saving command to reduce power consumed during operation of the refrigerator.

As shown in FIG. 37, when a ‘set’ button of the smart power saving operation button 3116 provided below the virtual refrigerator is selected, a power saving mode selection popup window 3701 may be displayed for selecting a power saving mode. The power saving modes displayed on the popup window 3701 may include a midnight power saving mode, a user power saving mode and an auto power saving mode.

As shown in FIG. 38, when a user selects the midnight power saving mode from the power saving mode selection popup window 3701 and touches a confirmation button 3801, a midnight power saving function may be executed. The midnight power saving function minimizes operation of the refrigerator in a predetermined time period around midnight (for example, from midnight to 4:00 am) to minimize a power consumption rate.

In general, the frequency of use of the refrigerator is remarkably reduced in the midnight time period as users are sleeping. Therefore, the operation factor of the compressor, operation of the cold air fan or operation of the defrost heater in the midnight time period may be reduced as compared to the general operation mode, thereby reducing power consumption.

For example, when a user opens and closes the door of the storage chamber in the day time or the night time other than the midnight time period, the temperature in the storage chamber is raised and such rise in temperature may act as load. In order to reduce the effects of such a load, the compressor may be operated or the cold air fan may be operated to supply cold air.

However, when the midnight power saving mode is selected, even if the temperature of the refrigerating chamber or the freezing chamber is raised, the compressor or the cold air fan is not immediately operated as long as the temperature does not exceed the upper limit of a set inner temperature range of the refrigerating chamber 5 (with reference to FIG. 1) or the freezing chamber 6 (with reference to FIG. 1). Only when the temperature of the refrigerating chamber or the freezing chamber reaches the upper limit of the set inner temperature range of the refrigerating chamber or the freezing chamber, is the compressor or the cold air fan operated. Since immediate load is eliminated during operation in the midnight time period, as described above, power consumption caused by the load may be reduced.

As shown in FIG. 38, when a user selects the midnight power saving mode 3801, a message 3810 ‘midnight power saving’ is displayed on the menu 3101 of the refrigerator management menu, thereby notifying the user of midnight power saving operation.

FIGS. 39A and 39B illustrate selection of the user power saving mode so as to execute power saving operation in a time section selected by a user. As shown in FIG. 39A, when the user selects a user power saving mode 3901 on the power saving mode selection window and touches a time change button 3902 to set a time period for power saving, a time setting window 3910 to set a time period is displayed.

On the time setting window 3910, the user may set one time period or plural time periods as power saving time. Here, the set time period may be a time period when the user does not frequently use the refrigerator, for example, during overnight hours or work hours. As shown in FIG. 39B, when the user sets a time period and touches a confirmation button 3911, a message 3920 ‘user power saving’ is displayed on the initial picture of the refrigerator management menu. Here, power saving operation may be executed so as to cause the minimum power consumption within the set temperature range of the storage chamber, by lowering the operation factor of the compressor or lowering the operation performance of the cold air fan during the time periods set by the user.

FIG. 40 illustrates selection of the auto power saving mode on the power saving mode selection window. When the user selects an auto power saving option 4001, a brief description of auto power saving and a power condition and charge information notification button 4002 may be displayed.

The auto power saving function relates to power saving operation of the refrigerator based on information regarding a time zone having the highest electric rates (utility costs) which is recognized by a server communicable with the refrigerator and is transmitted to the refrigerator.

That is, the auto power saving function may be configured to apply to the refrigerator the trend of electric rates toward a change from a fixed charge system unrelated to season and time to a variable charge system variable according to season and time. The auto power saving mode may vary the operation of the refrigerator based on the cost of electrical power. For example, when the electric rates are relatively high, the auto power saving function may increase the set temperature of the refrigeration chamber and the freezing chamber by a predetermined amount. The predetermined amount may be an amount which may not be readily noticeable to the user. Likewise, when the retrieved electric rates are relatively lower, the set temperatures of one or more of the refrigeration chamber and/or the freezing chamber may be increased or returned to the desired values. Based on the electric rate, the set temperature of the freezer chamber alone may be adjusted, or both set temperatures of the freezer and refrigeration chambers may be adjusted.

Moreover, the operational rate of the compressor and/or cold air fan may be adjusted based on the received electric rate information. For example, when electric rates are relatively low, the operational rate of the compressor and/or the cold air fan may be increased to optimize for performance. Likewise, when electric rates are relatively high, the operational rate of the compressor and/or the cold air fan may be reduced to optimize for energy conservation.

The server may control the operation of the refrigerator in the auto power saving function, e.g., to adjust the set temperature or operational efficiency to optimize power consumption of the refrigerator based on the electric rate. In one embodiment, the user may control operation based on the electric rate or effective cost. The user may set the level of the electric rate or effective cost at which the set temperature of the refrigerator may be automatically adjusted. For example, the user may configure the set temperatures to be adjusted when the electric rate increases by more than 10% above a preset rate. The user may also set the amount in which the set temperature may be adjusted.

If the refrigerator is operated in the auto power saving mode, an auto power saving notification message 4010 may be displayed on the main setting window of the refrigerator management menu, as shown in FIG. 40.
